1 Application filed. December 6, 1907. Serial No. 405,398.

To all whom it may concern:

Be it known that I, JAMES E. Buizen, a citizen of the United States,residing in Lincoln, in the county of Lancaster and State of Nebraska,have invented a new and useful Improvement in Ringing-Machines, of whichthe following is a specification.

My invention relates to improvements in rotary pole changers of thattype comprising a motor, a motor circuit, a circuit maker and breakermounted upon the armature shaft of the motor7 a bell circuit7 andbrushes included in the bell circuit and contacting with the circuitmaker and breaker.

The object of my invention is the provision of a simple. durable andefficient frame structure for a rotary pole changer of the above statedcharacter.

The invention consists of the construction, combination and arrangementof parts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, wherein z- Figure 1 is a view in side elevationof a rotary pole changer embodying my invention. Fig. 2 is a view inside elevation thereof. Fig. 3 is a top plan view thereof. Fig. t is adetail side elevational view of the circuitbreaker and maker. Fig. 5 isa sectional view of one of the bell circuit brushes.

My improved frame structure comprises a circular base. 1, and aninverted U-shaped member 1 secured at its ends to the base 1 by bolts1b. A bearing member 6 (see Fig. 4 of the drawing) is provided with ascrew threaded stem 6a through the medium of which it is secured to thebase 1. To permit of its application and removal and to permit of itsadjustment by means of a wrench7 the bearing member 6 is provided withan angular portion 6b. 1n its upper surface the bearing member 6 isprovided with a socket for the reception of a jewel bearing 6. The lowerend of an armature shaft is journaled in the bearing 6 and the upper endof the shaft is recessed as at 6d for the recept-ion of the lower end ofa bolt 7 which is threadedly mounted in the cross bar of the member 1a.To permitv of its adjustment the bolt 7 is provided with a milledoperating head 77 and the bolt is secured in its adjusted positionthrough the medium of a jam nut 7 I The drum armature 8 of a motor issecured to the shaft 5 and is located within a easing 2. The motorcasing 2 carries the field coils t and is secured to the sides of themember 1a through the medium of arms 2a. The arms are formed integrallywith the motor casing 2 and project in opposite directions therefrom.The arms 2 are provided with enlarged attaching flanges 2b, bolts 2Cpassing through the sides of the frame 1a and engaging the attachingflanges 2l. An arm 8 extends downwardly and forwardly from the cross barof the member 1a and carries the brushes Q of the commutator 10. Themotor is supplied with current froin a battery 21, wires 22 leading fromthe battery to the armature brushes 9. and wires 23 lead from the wires22 to the tield coils 4. The motor is of the usual construction andmounted upon the armature shaft 5 thereof is a circuit breaker and makerof the usual construction.

By reference to Fig. 4 it will be seen that the circuit breaker andmaker comprises metallic contact cylinders 1Q, and metallic contactlingers 13 separated by insulation 11. The brushes 16 and 18 of a bellcircuit contact with the cylindersl 12 and are con; nected to the bellbattery by wires '24. The brushes 17 and 19 of the bell circuit contactwith the lingers 13 and are connected to the bell by wires Q5. Thebrushes 16, 17 and 1S are carried by a vertical standard 15 which isprovided at its lower end with a horizontally disposed attaching flange15u. The standard 15 is secured to the base 1 through the medium of abolt 15" which passes through the base and through the `flange 15a. Thebrush 19 is carried by a` vertically disposed standard 2O which isprovided at its lower end with a horizontally disposed attaching flange20, this standard being secured to the base by a bolt 20" which passesthrough the base and through the flange. Each of the brushes 16, 17, 1Sand 19 comprise a cylinder a. mounted in the sleeve of insulation whichis located in an opening 15 formed in the standard. The sleeve a.carries a brush (l and a threaded bolt 15d. and mounted between thebrush and the bolt is a coiled expansion spring 16. The bolt 15d retainsthe spring 16 in applied position and provides means by which thetension of the spring may be adjusted. The bolt is held against movementby a jam nut 15e. The pole changer is adapted to be secured in appliedposition through the medium of bolts l passing through the base 1 andengaging a suitable support.

From the foregoing description, taken in connection with theaccompanying drawings, it should be apparent that I provide a iframestructure Which Will permit the parts of a rotary pole changer to becompactly assembled, and which is simple, durable and ehcient.

Having thus described the invention, what I claim is A frame structurefor pole changers, co1n ment with the bearing, a motor casing, armssecured to the ends of the motor casing and extending in oppositedirections therefrom, attaching lianges secured to the ends of the armsand secured to the sides of the U- shaped member, and verticallydisposed brush supporting standards, each standard being` provided witha horizontally disposed attaching ange secured to the base.
